Topography And Geological Body 3d Visualization Research And Application

control, and demonstrates the need to develop 3D terrain GIS activeX control.Analyzing the data structure of geological exploration domain, a 3D modeling method adapting to stratum is proposed: first fitting the various strata by Dem based on the tiered data of the bores, displaying synchronously the every Dem facial model, then sewing them to form entity. The geological 3D visualization System is developed with component technology based on the data model, 3D modeling method and visual technology, which has the function to read the original data of geological exploration, simulate and display 3D strata, display section and et al..The 3D visual technology on the terrain and the geological body in geoscience domain can understand the geoscience information more roundly and exactly, analyse geoscience rule, then make decision for producing and micro planning in geoscience domain.
